iwmc3200wifi: Add wifi-wimax coexistence mode as a module parameter
Wifi and wimax coexistence mode is set by wifi at boot time. There can be several modes, defined by priority tables. User space components can decide which one to select by writing to /sys/module/iwmc3200wifi/parameters/wiwi with this patch, before bringing the interface up.
